Thermal Store guide

Multiple heat sources into a vented
cylinder for mains pressure hot water

All the advantages of mains
pressure hot water, none of the disadvantages of unvented cylinders

Thermal store - the safe way to
produce mains pressure hot water

Mains pressure hot water is a
luxury worth considering. Hot water at the same pressure as the
cold water yields a number of advantages: balanced supplies of
hot & cold water, no need for shower booster pumps, quicker fill
time with a bath, the list goes on.

There are however different ways
to achieve mains pressure hot water. You can either go the
'unvented' route (a route you should fully understand before
selecting) or the 'Thermal Store' route that is inherently
safer.

Thermal stores offer other
advantages besides safety.

They can accept several heat
sources simultaneously. These heat sources can even be those
deemed uncontrollable and therefore unsafe to feed into an
unvented cylinder.

The open vented nature of a
thermal store allows it to accept heat from devices such as a
wood burning stoves or an AGA without fear of explosion from
over-temperature and/or pressure.

Thermal stores can even be
incorporated into the grand scheme of your household central
heating system. With all heat sources feeding into the thermal
store it is possible to run your heating circuit directly from
the cylinder - supplying preheated water straight to radiators,
improving response time dramatically.

Consider, a central heat store
into which to feed any and all heat sources and in return you
get mains pressure hot water and the chance for your wood burner
or AGA to centrally heat your home. Thermal stores can even be
heated by solar energy.

Having none of the risks
associated with unvented cylinders and all these advantages,
thermal stores are rapidly becoming the cylinder or choice. You
decide!

Choose your Thermal Store

Newark Thermal Store

Gledhill Thermal Store

A range of quality thermal
stores built in the UK that include direct, indirect and
solar models. As well as the traditional 'cylinder type'
This range also offer a combination version (shown) that
incorporates a top mounted F&E tank necessary for
operation.

Newark
thermal stores are supplied with a thermostatic mixing
valve (to stabilise output temperature), a check valve
and a pressure regulating valve for the mains pressure
inlet (to prevent damage to the heat exchanger). The
combination header unique to this cylinder removes the
need for a remote tank. The cylinder type will require a
remote F&E tank.

Gledhill offer their
premium Torrent Multifuel thermal store. Gledhill, a
major UK manufacturer, have concentrated on presentation
by encapsulating the store in a plasticised metal
sleeve. This offers a certain aesthetic appeal and some
mechanical protection but does not affect or contribute
to the function.

The Torrent Multifuel thermal store is supplied with a
thermostatic mixing valve (to stabilise output
temperature). Any other components, such as check valve,
regulating valve and F&E tank must be purchased
separately.
